Abstract
The invention relates to an organic polymer composite material, in particular to a halogen-free glass fiber enhanced nylon 66 material and a manufacturing process thereof; the halogen-free glass fiber enhanced nylon 66 material is composed of the following ingredients by weight ratio: 52.5-95 percent of nylon, 5-45 percent of alkali-free glass fiber, 0.1-3.0 percent of heat stabilizer, 0.1-3.0 percent of glass fiber treating agent and 1.3-5.5 percent of other agents; the halogen-free glass fiber enhanced nylon 66 material and the manufacturing process have high performance, high impact and not obvious brittleness compared with unimproved similar material, especially, at below zero low-temperature environment, the brittleness of the similar material is overcome; in addition, the production procurement is convenient, the material and the process are in accordance to other environment protection requirements, thereby completely improving the product competitiveness.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of halogen-free glass fiber enhanced nylon 66 material and preparation method thereof.
Background technology
At present, application with the alternative natural materials of plastics constantly enlarges in the world, scientist all over the world actively seeks new high-performance thermoplastics and comes alternative metals and timber by various tests, and this also becomes enterprise and strives for more families and the important component part of extending volume growth.
It is possible that the development of high temperature plastics changes into more microminiaturized lightweight of industrial or agricultural and civilian installation and powerful.High-temperature resistance plastice can bring higher heat resistance for some parts, or simply having substituted raw material metal produces these parts.The equally also useful high-temperature resistance plastice of the device of novel appts and assembly replaces the trend of metal and thermosetting material.These all will strengthen the demand to the high-temperature resistance plastice material, thereby drive the market requirement.
Glass fiber reinforced nylon 66 is to use one of maximum several engineering plastics at present, and this class material is widely used in every field, is seen everywhere in industry and our daily life.And Europe/Japan or the like developed country has started all restrictions of foreign imported product for various reasons at present, has set up a series of barrier, wherein, to the material Halogen requirement of electric equipment products, is exactly one of them.Therefore cause the more export enterprise of China is seriously perplexed.
But the high-temperature resistance plastice material of all kinds all has a common shortcoming in the existing market: impact lowlyer, fragility is obvious, and is especially when the sub-zero temperature environment, crisp more partially.The bigger range of application that has limited high temperature plastics alternative metals and timber of this shortcoming.And these the problem to be solved in the present invention just.
Summary of the invention
The objective of the invention is to effectively overcome the defective of prior art, a kind of halogen-free glass fiber enhanced nylon 66 material of modified form is provided.
Technical scheme provided by the invention is as follows: halogen-free glass fiber enhanced nylon 66 material, form nylon 66:52.5-95%, alkali-free glass fiber: 5-45% by weight by following composition; Thermo-stabilizer: 0.1-3.0%, glass treatment agent: 0.1-3.0, other auxiliary agents: 1.3-5.5.
The preparation method of halogen-free glass fiber enhanced nylon 66 material of the present invention, comprise the steps: earlier with nylon 66, environmental protection glass, thermo-stabilizer, glass treatment agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, naturally place after 6 hours and carry out mixing extruding by side adding environmental protection glass through twin screw extruder under the screw combinations situation that medium tenacity is sheared again, the pelletizing of water-cooled tie rod makes a kind of halogen-free glass fiber through screening and dewatering again and strengthens the environmental protection nylon 66 material.
The present invention has effectively overcome the defective of existing nylon material, has the following advantages:
A kind of halogen-free glass fiber enhanced nylon 66 material of the present invention, performance is compared with the same type of material of not improvement, impact higher, fragility is not obvious, especially when the sub-zero temperature environment, overcome the crisp partially shortcoming of same type of material, and production procurement is convenient, also meet simultaneously other all environmental requirement, comprehensive like this product competitiveness that improved.
Embodiment
Below be the embodiment of halogen-free glass fiber enhanced nylon 66 raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of halogen-free glass fiber enhanced nylon 66 raw material is provided, and forms nylon 66:65%, environmental protection glass: 30% by weight by following composition; Thermo-stabilizer: 1.5%, the glass treatment agent: 1.0%, other auxiliary agents: 2.5%;
Earlier with nylon 66, thermo-stabilizer, glass treatment agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, stainless steel, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder even substantially, do not have obvious agglomerate or gather, place naturally then and re-use after making its sufficient reacting in 6 hours; Twin screw extruder uses 36 length-to-diameter ratios, and medium tenacity is sheared; The environmental protection glass is added in proportion by the side; Keep vacuum state and 290 the degree condition is mixing extrudes; Adopt water-cooled tie rod pelletizing mode, promptly make halogen-free glass fiber enhanced nylon 66 material through screening and dewatering.
